If a woman is having a urine pregnancy test and its result suggests negative HCG, it often means that she is not currently pregnant, but not necessarily not pregnant. This is because it is possible that the HCG hormone in the urine is not yet elevated due to the short period of menopause, but is pregnant. Therefore, a urine pregnancy test is not the most accurate way to check for pregnancy, especially for women who usually have irregular menstrual cycles and do not use birth control during intercourse. Often, a urine pregnancy test should be considered 16 days after the last intercourse, or a blood HCG test 11 days after the last intercourse to confirm the diagnosis, and only if the blood HCG is not pregnant, then the pregnancy is really not there.
